- a valve has a valve housing with at least a first and a second
- a closing member assembly is provided with a closing member which is movable along an axial direction.
- a closing member In the context of this axial mobility, it can be brought into a closed position, in which it cooperates sealingly with a valve seat arranged between the connections, whereby a fluid connection between the first and second connection is prevented.
- the axial movement of the closing member can be effected from outside the valve housing.
- this is a fluid-operated drive is used, in which the pressure medium exerts a pressure on a piston against the restoring force of a spring.
- valve Special requirements for the valve are aseptic applications, for example in the food industry. In such applications, the contact of the product with ambient air should be avoided, otherwise bacteria and germs in the product
- the design of the seal in the valve is correspondingly complex. This includes the sealing of the closing member assembly against the environment of the housing, especially where the closing member assembly is connected to the drive.
- DE 102007014282 A1 proposes here a fluid-impermeable membrane, which is held on the closing element arrangement on the one hand and a valve housing-side holding arrangement on the other hand with a sealing effect.
- the holding arrangement has a clamping gap oriented obliquely to the axial direction.
- the membrane comprises a clamping section extending in this clamping gap and a central opening, which is separated from the
- Closing member arrangement is interspersed.
- the sealing effect results from holding the central opening on the closing element arrangement and the clamping section in the clamping gap.

- Clamping gap is provided a projection which increases the clamping force. It is the object of the invention to provide a valve with membrane and a membrane which further improve the valve housing side sealing of the membrane over the prior art and thereby reduce the need for maintenance.
- the membrane according to the invention has a first section which is arranged on a radially outer edge of the membrane and to which a second section adjoins radially inwardly. Both sections are arranged at an angle to each other.
- the first section is clamped in the retaining arrangement of the membrane, while the second section is at least guided.
- the angle between the sections is dimensioned so that there is a positive connection between the holding arrangement and the sections.

These are recessed in that on a radially outer edge of the membrane, a first portion is provided, which is followed radially inward by a second portion which is at an angle to the first portion which is dimensioned so that the first portion and second portion forming a positive connection in the holding arrangement are receivable.
- This type of shaping which is created in the manufacturing process of the membrane and before installation in a valve, reduces the load on the membrane in the installed state, since preforming takes place during the manufacturing process instead of permanent deformation. A sustained, heavy load is prevented in this way, thus the
- the angle between the first and second sections is between 60 ° and 135 °.

- channel 180 may be formed in the second housing member 162, for example, radially inwardly in the direction of the second decoupling element 136, and cooperate with a passage 214 in the membrane 200. Should product reach the intermediate space between the diaphragm 200 and the valve housing 160, it can be discharged through the passage 214 and the passage 180 out of the space between the valve housing 160 and the second housing part 162.
- the contours are formed by walls, as can be better seen from the detail view in FIG.
- the contour on the second housing part 162 is formed by a first clamping gap wall 220, a first guide wall 228 and a first wall 224, which adjoin one another and are at different angles to one another.

- the clamping gap has in the sectional view an extension direction E, which is aligned at an angle K to the axial direction M. This angle K may preferably be in the range between 30 ° and 60 °, preferably 45 °. This reduces the stress on the membrane 200.
- a first portion 202 of the membrane 200 is located in a first gap formed between the first wall 224 and the second wall 226.
- the arrangement is dimensioned such that the force exerted indirectly on the second housing part 162 causes a clamping of the first portion 202 between the first wall 224 and the second wall 226.
- a second portion 204 of the membrane 200 is located in a second gap formed between the first guide wall 228 and the second guide wall 230. Clamping may be effected but the second portion 204 is guided at least through the walls 228 and 230. From the orientation of the walls 224, 226, 228 and 230 results in an arrangement of the first portion 202 and the second portion 204 at an angle V to each other.
- This angle V is dimensioned such that from the first section 202, the second section 204 and the walls 224, 226, 228 and 230 a positive connection is formed and in this way the membrane 200 is fixed in a form-fitting manner in the holding arrangement 120.

It can be 90 ° for easy production, of which a few angular degrees of deviation are still detected. This preformed angle W can deviate from the angle V of the holding arrangement. A particularly easy and safe mountability is achieved when the angles W and V come close to a few degrees, for example, have a deviation of less than 10 °. This also reduces the material stress resulting from deformation during installation.
